import * as cdk from 'aws-cdk-lib';

const app = new cdk.App();
const stack = new cdk.Stack(app, 'Stack', { env: { region: 'us-west-2' } });

const globalTable = new dynamodb.TableV2(stack, 'GlobalTable', {
  partitionKey: { name: 'pk', type: dynamodb.AttributeType.STRING },
  billing: dynamodb.Billing.provisioned({
    readCapacity: dynamodb.Capacity.fixed(10),
    writeCapacity: dynamodb.Capacity.autoscaled({ maxCapacity: 15 }),
  }),
  replicas: [
    {
      region: 'us-east-1',
    },
    {
      region: 'us-east-2',
